TROLLEY.

$PEGIFIGATION forming part of Letters Patent No. 538,295, dated April30, 1895.

Application filed October 29, 1894. serial No. 527,227. (No model) Toall whom it may concern.-

Be it known that I, J UDSON D. SWACICK, a citizen of the United States,and a resident of Canton, county of Stark, State of Ohio, have inventeda new and useful Improvement in Trolleys, of which the followingis afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to improvements in trolleys for electric railwaycars.

The object of the invention is to provide adjustable journal bearings,and means for oiling the bearings.

With these objects in view, my invention consists of certain features ofconstruction and combination of parts as will be hereinafter describedand claimed.

Figure 1, of the drawings is a perspective of my invention. Fig. 2, is atransverse section through the wheel and frame. Fig. 3, is a plan viewof the wheel, showing the central recess. Fig. 4, is a perspective ofthe cap for the recess or sideof the wheel, with one side of thebearing. Fig. 5, is a similar view of a small thimble or cylinder,adapted to receive the points of the spindles.

A represents the frame or trolley wheel support, formed in two parts,which are secured together, and to the trolley pole B by the bolts a. Atthe upper end portion of the frame, are provided conical spindles O, 0',secured in the frame by the set screws 2). The top portion of the frameis circular in outline, and flanged in toward the wheel as shown at o,for the purpose of preventing the trolley wire getting between the wheeland the frame, and at the lower end portion of the frame,

inwardlyprojected studs d are provided, that determine the distancebetween the two sides, and a support against which the bolt may bedrawn, to'secure the parts in desired relation.

In the trolley wheel X is provided a conical socket D, adapted toreceive the conical spindle O, and in the removable side E, of the wheelis provided a similar conical socket D for a similar conical spindle C.On the inside face of the removable side E, is provided a cylinderportion F, integral with the side,

that rests on a packing ring (1, when the cap or side is placed inposition as shown in Fig.

2. For the purposes of this application, I

have formed a screw thread about the edge of the removable side E, andin the edge of the recess in the side of the wheel X, and secured by theset screw e, thus forming an oil chamber G, about the cylinder F, whichis provided with apertures f, to allow oil to pass from the outerchamber G, to an inner chamber H.

The small cylinder or thimble J, is placed in position shown in Fig.2,before the side piece E is placed in operative position. The endportions of the spindles O and 0', pass into the ends of cylinder J,which .is provided with slots h, that admit oil to the spindles. Thechamber H should be packed with mineral wool, to prevent too free a flowof oil, to the spindle.

The spindles G and O, are adjusted in'the conical sockets or journalboxes D and D, by the through boltKas shown in Fig. 2,the thread beingturned into a threaded portion, provided in spindle C. To supply thewheel with oil, the screw 6 is removed, and the recess G filled and thescrew returned to secure the side E in position.

Having thus fully described the nature and object of my invention, whatI claim is.

1. The combination in a trolley of the supporting frame A, havinginwardly directed conical spindles, the Wheel X, having a removableside, cylinder F, conical sockets or bearings adaptedto receive thespindles, the oil chamber G, and means for adjusting the spindles in thesockets, substantially as described and for the purpose set forth.

2. The combination in a trolley, of a supporting frame, spindles securedthereto, a wheel composed of two parts, one part being provided with anoil chamber and with a screw thread edge and the other part having athread edge to take the threaded edge of the chambered part, and a setscrew subserving the double purpose of preventing the two parts of-thewheel unscrewing, and to afford means for allowing a lubricant to beintroduced into the chamber, substantially as described.

.3. The combination in a trolley, of the supporting frame, havingsecured thereto, inwardly directed conical or tapering spindles,

a wheel as X, having in the sides thereof, tapered sockets or bearings,an oil reservoir G, an inside oil chamber H, and means for securing thespindles and bearings in desired adjustment, substantially as describedand for the purpose set forth. 7

4. The combination in a trolley of the supporting frame, having securedthereto inwardly directed conical or tapering spindles, a wheel havingin the sides thereof, and central thereto, conical sockets, adapted toreceive the conical spindles, a removable side and bearing, an apertnredinwardly projected cylinder F, oil reservoir G,'oil chamber H, aperturedsleeve J adapted to receive the end portions of the spindles C and 0',means for securing the removable side E, to the side of the wheel, and ameans for adjusting the spin" dles to the hearings in the wheel;

5. The combination in a trolley of the frame having bearings at itsupper end, tapering hollow spindles seated therein, set screw forholding the spindles in said bearings, awheel having tapering hearingsto receive the tapering spindles, and a through bolt passing throughsaid spindles whereby they may be adjusted in the wheel bearings,snbstantiall y as described.

In testimony whereof I have hereunto set my hand this 12th day ofOctober, A.D.1894.
